Your installation failed (and you didn't notice). It HAS to complete right through to asking you for the admin profile and then the name of the site. I expect you didn't get that far.
There's no point trying to patch up a broken installation.
It's all in the installation instructions but...
- make very sure you meet all the requirements for your version of Moodle
- delete the database and create it again, empty
- create the config.php by copying config-dist.php to config.php
- edit config.php and put in all your parameters (it is very well commented). Find the debugging section and uncomment the debugging lines
- try again
This time watch carefully for errors.
